The Linux display server protocol Wayland is now supported. Tested together with Gnome 3.22.2.

As in Helen 2.5 there are two Linux Intel packages with embedded Java runtime, one for 32-bit and one for 64-bit.
To determine whether your Linux kernel is 32- or 64-bit, you can issue uname -m on the command line. The result x86_64 means a 64-bit kernel and
i686 a 32-bit kernel. If you don't mind to edit a configuration file you can of course always use the install package without bundled Java
runtime instead.

Helen 2.7 now supports OS X 10.11
Starting with Helen 2.5 Mac OS X 10.6 or older are no longer supported due to technical reasons. If you use Mac OS X 10.6 or older please use a previous Helen version.
Like in the version before, Helen for Mac bundles now a version of the Java Runtime, an installed version of Java on the system is not required.

button. The icon of the button looks like:
